/** Test for Bug 682592 **/

/* 
   We want to check that bidi is detected correctly. So, we have a reference
   document where ltr is set explicitely with <bdo> element. Then, we compare
   it with test document.

   In mozilla, once bidi has been detected in a document, document always
   consider it's in bidi mode. So, if one fragment enables bidi correctly, and
   we create or update a fragment in the same document, that operation may not
   enable bidi by itself, but it will not be detected. So, we need to have new
   document for each test.

   So, instead of many diferent reftests, this mochitest implements a
   reftest-like. It creates reference text fragments in reference iframe, test
   text fragments in test iframe, and compare the documents. Then, it reloads
   test iframe. Reference iframe does not need to be reloaded between tests.
   It's ok (and maybe, desired) to keep bidi always enabled in that document.
